What are gaseous extinguishing systems and why do they leak?

Gaseous extinguishing systems protect urgently important infrastructure against special hazards, fundamental for the safeguarding of critical facilities. However, gaseous extinguishing systems leak because they are active and dynamic systems and this threatens the consistent and reliable safety that they should offer to the space that they protect.

In fact, in the regulation ISO 14520, which is the “gold standard” of fire suppression systems, it is clearly stated that gaseous systems leak and need to be periodically checked to counter this issue:  - “if a container shows a loss of agent in quantity of more than 5 % or a loss of pressure of more than 10 %, it shall be refilled or replaced.”

Given that gaseous systems are designed specifically for a protected space or room e.g. one aluminium foundry factory floor, a 5% loss of extinguishing agent may mean that the system would not fully extinguish the fire.

Technology now exists to improve the reliability of fire suppression systems that affects the safety of all who occupies the building it protects in an event of fire.

To  ensure  that fire  suppression  systems  are  always   full and that no accidental discharge or leakage has occurred, Coltraco Ultrasonics have developed an ultrasonic liquid level indicator, the Portalevel ® MAX and  the constant monitoring system the Permalevel ® MULTIPLEX. By testing and monitoring fire extinguishing systems for leaking, facilities managers and factory owners are able to exceed  standards and ensure that the gaseous extinguishing systems are able to extinguish in the event of the fire.

The easy to use Portalevel® MAX uses ultrasonic technology to pinpoint the liquid level of suppressant agent in the cylinders of the extinguishing system which makes testing is quicker and easier. Liquid level identification takes just 30 seconds, needing only one person. Combined with the Portalevel® MAX, the Portasteele® Calculating fire suppression agent weight is an advanced calculator application, that converts the liquid level height of C02, NOVEC™ 1230 and FM-200® liquefied gaseous extinguishant agent readings taken on an ultrasonic non-destructive liquid level indicator device into the agent weight/mass.  Furthermore, the Portasteele® CALCULATOR can convert an expected agent weight back to the required liquid level allowing users to anticipate where the level should be.


CEO Message

Integrity and Science Key to Our Culture of Performance

Dear Coltraco Customers, Strategic Partners and Distributors,

Integrity is our defining value. Performance is its consequence. We understand that our customers have choices, and how we perform determines whether customers choose us. Coltraco’s Code of Ethics does not merely require compliance with laws. It embodies a Commitment to positive behaviours that build trust, promote respect, operate with distinction, with courtesy and global levels of performance, demonstrating our integrity and delivering customer performance.

We honour our commitments, communicate transparently, and act with honour. Ethics are the foundation of our performance culture and our science-based approach. We lead in specific technologies delivering the watertight integrity monitoring of marine structures and the monitoring of fixed liquefied gaseous fire extinguishing systems and the room integrity of protected space to ensure agent hold-times post-installation. We show this by our understanding of the science in them and the mathematics that explain them.

I would like to thank you for your business and for the relationships with our Customers, Strategic Partners, Distributors and ODAs who we value so highly.

My kindest regards,
